The Benchmade Knife Company designed the Infidel to be a top-notch automatic knife with tactical applications in mind. This marvel of knife engineering features a quick-opening, double edged dagger that looks as good as it functions.

Its out-the-front (OTF) double-edged spear-point steel blade was built for unwavering strength and reliability. The D2 high carbon steel used in this blade has excellent abrasion and compression resistance—in fact, this type of steel is commonly used to form and cut softer steel and other metals.

The handle’s Presidio bi-directional tread pattern style ensures you have a firm, comfortable grip even with gloved hands. The effortless feel of the ambidextrous forward release slide deploys the blade quickly and then locks firmly with a solid three-point retention system to provide on-demand dependability, whatever your situation. Simply reverse the slide motion to retract the blade just as fast.

Benchmade has also equipped the Infidel with a steel deep-carry pocket clip for easy transportation and concealed carry capability, plus a MOLLE compatible soft knife sheath.. It’s an intimidating product on offense or defense.
